Question

What kind of triangle has the angles: 121°, 34° and 25°?
To help: Acute, obtuse, or right.

Answer 1

Answer:

Area: T = 11.977

Perimeter: p = 17

Semiperimeter: s = 8.5

Step-by-step explanation:

Angle ∠ A = α = 34.772° = 34°46'19″ = 0.607 rad

Angle ∠ B = β = 58.811° = 58°48'41″ = 1.026 rad

Angle ∠ C = γ = 86.417° = 86°25' = 1.508 rad

Height: ha = 5.988

Height: hb = 3.992

Height: hc = 3.422

Median: ma = 6.205

Median: mb = 4.848

Median: mc = 3.708

Inradius: r = 1.409

Circumradius: R = 3.507

Answer 2

Step-by-step explanation:

121°+34°+25°= 180° which is clearly denotes no one from three all because for to be obtuse anɡle should be less than 180° but its equals to 180° which is not possible
